External processing 8.3?

Question

1C-Enterprise

Good afternoon! I started to master 1s quite recently and faced the following task: you need to write an external processing that will display in its tabular part from the document Receipt to the Settlement Account the contract of the counterparty in one column and where exactly the contract is taken from in the document (from the account, details, tabular part of the document) in the second column. Do not display empty documents. Created a form with the ability to select the desired document. I added a button C to generate on the form, when you click on it, the necessary functionality will be carried out. How to correctly set the commands that it should execute?

Answer 1

Thank you, Alexander, just such a specialist set the task, but I have to figure it out myself, I would like a piece of code, for clarity)

Answer 2

Commands are attached to the button, procedures of the form module are attached to the commands, from these procedures you can already access the rest of the configuration objects. In general, you should start with a command, not with a button. By dragging a command onto a form, you will generate a button, plus you can generate a procedure in the form module from the same command in one click.
In general, your question is very extensive, and the task is somewhat more difficult than for a person who has recently begun to study 1C, it is difficult to answer in a nutshell. It is best to contact a specialist who will clearly show how this is all done, or, ideally, go to courses from the 1C company itself. Hope it helped a little.
